SWITCH AND HOUSING CONSTRUCTION THEREFOR.

Application flied May 3,

To all 'whom t may concern:

Be it known that I, CARL H. BIssELL, a citizen of the United States, anda resident of Syracuse, in the county oi'. Onondaga and State of NewYork, have invented a certain new and useful Switch and HousingConstruction Therefor, of which the followingr is a specification..

This invention has for its object a. switch and housing constructiontherefor particularly applicable for use in connection with electricheadlights of locomotive, electric cars, etc., where ruggedness andsimplicity are factors, which construction is .especially simple andhighly efficient and durable.

The invention consists in the novel features and in the combinations andconstructions hereinafter set forth and claimed.

ln describing this invention. reference had to the accompanying drawingsin which like characters designate correspondingr parte in all theviews.

Figure 1 is a front elevation, partly in section, of a switch embodyinglmy invention, the box therefor being shown in section and the cover ofthe box as brokenv away.

Figure 2 is a. vertical sectional view taken centrally or' Fig. 1.

Figu re 3 is ay front elevation of the entire switch constructionincludingV the housing therefor.

This invention comprises a` switch having; movable member or switcharm.` a handle connected t0 said member and having' a movement in adirection at an angle to the shitting: movement of the handle, a springttor efiecting such movement. and a. sum".r against which the springrholds the handle.

l designates the hoX in which the switch housed, said box having meansas one or more nipples 2 Yfor connection to conduits enclosingr theservice wires. The box' is open at its front side and said side providedwith a cover 2 secured in position in any suitable manner as by screwsIt.

The switch here shown is a double throw knife switch and comprises ahase 5 of iii-- sulation mounted in the box ou one of the walls adjacentthe open side. contacts 6. T mounted near opposite ends of the base. aconductor 8 mounted on the base between the contacts, a` switch memberor arm Sa hinged to the conductor and movable into 1919. Serial No.294,581.

engagement with either`contact 6, 7 and a handle 9 for operating the arm8a.

The base is secured to the boX in any suitable manner, as by screws 10.The con* tacts 6, 7 are knife contacts and are held in position in anysuitable manner as by screws 11.

The conductor 8 is Z-shaped in general form, the base of the Z .beingmounted on the base 1 and secured thereto as by screws 12 extending fromthe rear side of the base. One arm of the Z-shaped conductor is providedwith a binding device 13.

The binding device 13 is for connection to a feed wire, not shown, bymeans of which the current is carried from the feed wire'to he conductor8 to one branch of the switch arm S, thence to the other arm to one ofthe contacts (i. 7, when the switch is closed. the arm 6^ being'U-shaped in order to proride two conductors, one of which coacts withthe conductor 8 and the other with the switch contact 6 or 7.

The switch member 8Pl is here shown as U-shaped and the arms thereof arepivoted to the arms ot the conductor 8 by a hinrfc pin. 14. and one ofthe arms of the switch member is movable into and out of engagement withthe contacts 6, 7. The switch member normally stands in neutral positionand is moved to neutral position from either side ot neutral by a spring15 coiled about theI hinge pin 14- and having its ends bearingrespectively on opposite edges of the arms of the U-shapcd switchmember.

The handle 9 is practically a crank handle mounted on the switch memberand havingr a yielding movement at an angle to the movement of theswitch arm, that is the handle vis movable radiallyrelatively to theairis of the switch member.

ln the illustrated form of my switch, the handle extends through aradial slot 16 in the trent arm oi' the switch member and is pivoted atits inner end to a lug 17 carried by the intermediate part of the switcharm and spaced apart from the front arm.

The handle 9 is moved inwardly radially bv a spring 1S connected at oneend to the handle` and at its other end to the hinge pin 14.

The handle projects through a slot 19 in the cover 3. Shoulders 20project into the slot neal` its opposite ends forming sockets or :seats2l into which the handle ratehets when shifted, in one direction or theother to engage the knife or switch member' with either eontsicts (i or'7; rlhe springY 18 pulls the handle against the upper side the slot andratchets it in the seat This` switch is particularly applicable forlighting and dimmingheadlights and in operation7 when the handle ismoved in one direction from central position, the switch arm engages thecontacts 6 to lgive ii'ull light and when moved in the oppositedirection from neutral engages the contacts 7 to dim the light. During;the movement of the handle it ratcliets automatically into one or theother of the seats 2l.` i

Tl". switch construction particularly advantageous in that it issimple,Y Strong and Weather tight and further in that it pro* vides enespecially simple look ttor holding the switch in its operativeposit-iene What l Claim is:
